[A Conventional Method of Displaying Services]

Before explaining an information processing system according to embodiments, first, an explanation will be given on a method of displaying registered services in a conventional information processing apparatus. FIG. 1 is an illustration for illustrating the method of displaying registered services in a conventional information processing apparatus.

In FIG. 1, a cellular phone 10 as an example of the conventional information processing apparatus includes an IC chip 20 and an application manager 30. The IC chip 20 includes a storage device (not shown), and a service registered in the cellular phone 10, such as an electronic money service, for example, uses an area A or an area B as a memory area of the storage device. Further, the IC chip 20 is an IC chip compatible to a plurality of applications.

The application manager 30 performs a management or the like of an application A40, an application B42, an application C44 and an application D46, which are installed on the cellular phone 10. In the application A40, the application B42, the application C44 and the application D46 there is described information on whether to use a memory area of the IC chip 20 and information on an address of the memory area to be used.

The application A40 is an application used by an electronic money service, for example, and owns the area A of the IC chip 20. The application B42 is an application used by other services, and owns the area B of the IC chip 20. The application C44 is an application used by the other services, and is an application which does not own the memory area of the IC chip 20 but uses the area B of the IC chip 20. The application D46 is an application used by services which do not use the memory area of the IC chip 20.

Since the application A40 and the application B42 owns the memory area of the IC chip 20, they can generate and delete the memory area, and read/write and refer to data or the like in the memory area. Since the application C44 does not own the memory area of the IC chip 20, they cannot generate or delete the memory areas, but can read/write and refer to data or the like in the memory area.

In the cellular phone 10 as the conventional information processing apparatus, by passing an application information describing that the application manager 30 uses the memory area of the IC chip 20, to an application (not shown) for displaying services, the application for displaying services displays services registered in the cellular phone 10 based on the passed information on the application. The application manager 30 has a function to restrict deletion of the application A40 that owns the area A, when the area A exists in the IC chip 20.

A form of services registered in a cellular phone as an information processing apparatus are becoming more diversified. FIG. 2 is an illustration for illustrating the form of services registered in the cellular phone as the information processing apparatus.

In FIG. 2, a cellular phone 100 as the information processing apparatus includes a Web browser or the like 110, an IC chip 120 and an application manager 130. The application manager 130 performs a manager or the like of an application A140, an application B142 and an application C144 which are installed on the cellular phone 100. The application A140 is an application used by the electronic money service, for example, and owns the area A of the IC chip 120. The application B142 is an application used by other services, and owns the area B of the IC chip 120. The application C144 is an application used by the other services, and is an application which does not own the memory area of the IC chip 120 but uses the area B of the IC chip 120.

In the cellular phone 100, there are registered services that use the memory area of the IC chip 120 which is used through the Web browser or the like 110 that accesses a service providing servers 600 and 602 capable of communicating with the cellular phone 100 via a communication network 710. This service is an example of a wire communication service of the present embodiment. The service providing server 600 is a service providing server that does not own the memory area of the IC chip 120 and that uses the area A of the IC chip 120. The service providing server 602 is a service providing server that owns an area C of an IC chip 120.

In the cellular phone 100, there are registered services which use the memory area of the IC chip 120, and which are available via non-contact communication with an information processing apparatus 510 having a reader/writer 500 capable of communicating in a non-contact manner with the cellular phone 100. Further, in the cellular phone 100, there are registered services which use the memory area of the IC chip 120, and which are available via non-contact communication with an information processing apparatus 512 having a reader/writer 502 capable of communicating in a non-contact manner with the cellular phone 100. In the present embodiment, the information processing apparatuses 510 and 512 are, for example, a PC (Personal Computer), a POS (Point of sale) terminal, an automatic payment machine or an automatic vending machine. This service is an example of a wireless communication service of the present invention. The information processing apparatus 510 is an information processing apparatus which does not own the memory area of the IC chip 120, but uses the area C of the IC chip 120. The information processing apparatus 512 is an information processing apparatus that owns an area D of the IC chip 120.

As described above, in the cellular phone 10 as the conventional information processing apparatus, an application (not shown) for displaying services displayed services registered in the cellular phone 10. Specifically, services registered in the cellular phone 10 were displayed based on the information passed from the application manager 30, the information which describes the memory area of the IC chip 20 will be used. However, services through the web browser or the like 110 accessed from the service providing servers 600 and 602, and services by a non-contact communication from the information processing apparatuses 510 and 512, shown in FIG. 2, do not use applications. Because of this, there has been a problem that services that do not use applications cannot be displayed in the conventional method of displaying services.

Then a later-described information processing system 1000 according to the present embodiment performs a later-described preliminary processing for displaying services and a processing of displaying services. This enables displaying all services including those which use the memory area of the IC chip 120 and do not use applications. Hereinafter, a main service means a service that uses an application which owns the memory area of the IC chip 120, or a service provided by a service providing server or an information processing apparatus, which own the memory area of the IC chip 120. Further, a related service means a service which does not own the memory area of the IC chip 120 and uses the application that uses the memory area of the IC chip 120, or services which are provided by the service providing server or an information processing apparatus which does not own the memory of the IC chip but uses the memory area of the IC chip 120.

[A Processing of Displaying Services]

Hereinafter, a processing of displaying services that the information processing system 1000 according to the present embodiment performs will be explained. This processing is a processing which is performed by the client application installed into the cellular phone 100. FIG. 7 is a sequence diagram showing a processing of displaying services according to the present embodiment. The processing of displaying services in FIG. 7 is a processing performed when the cellular phone 100 and the service information distribution server 200 are both online, and can communicate. Note that FIG. 10 is an illustration for illustrating a detail on the processing of displaying services in FIG. 7.

In FIG. 7, at first, the cellular phone 100 reads information for specifying the main service (hereinafter, referred to as “the main service identification information”) that obtains a memory area, such as a segment information of the memory area, for example, from the memory area of the storage device 184 of the IC chip 120 (step S201).

Next, the cellular phone 100 reads the version information of the main service information and of the information for specifying related services from the database 140 when the database 140 stores the main service information and the information for specifying related services (step S202).

Next, the cellular phone 100 transmits the main service identification information which has been read in step 201 to the service information distribution server 200 (step S203). Note that in step S203, when the database 140 stores the main service information and the information for specifying related services, the cellular phone 100 transmits the version information of the main service information and of the information for specifying related services, which has been read in step 202, to the service information distribution server 200 as well as the main service identification information.

Next, the service information distribution server 200 reads the service information of the main service shown in FIG. 12 from a service information database 210 based on the main service identification information that has been read in s201. When the service information distribution server 200 receives the version information of the main service information, the service information distribution server 200 reads the service information of the main service of the new version from the service information database 210. The service information distribution server 200 reads the information for specifying the related services shown in FIG. 13 from a related services specifying information database 220. When the service information distribution server 200 receives the version information of the information for specifying related services, the service information distribution server 200 reads the information for specifying related services of the new version from the related services specifying information database 220 (step S204).

Next, the service information distribution server 200 assigns a digital signature to the distribution information using the secret key which is registered in a signature key (secret key) repository 230 after being registered in step S102 of the preliminary processing of displaying services in FIG. 6 (steps S205).

Next, the service information distribution server 200 transmits the distribution information assigned with the digital signature to the cellular phone 100 (step S206).

If the main service information of the new version and the information for specifying related services are not transmitted from the service information distribution server 200 when the cellular phone 100 transmits the version information of the information for specifying the main service information and the related services to the service information distribution server 200 in step s203, the cellular phone 100 reads the information for specifying the main service information and the related services from the database 140 (step S207). When any information of the version newer than the main service information or the information for specifying related services which are stored in the database 140 is not stored in the service information distribution server 200, communication traffic with the service information distribution server 200 can be decreased since the cellular phone 100 does not receive neither the main service information nor the information for specifying related services from the service information distribution server 200.

Next, the cellular phone 100 performs a later-described processing of related service identification (step S208), and reads information for identifying related services that uses the memory area (hereinafter, referred to as “the identification information of the related services”).

Next, the cellular phone 100 transmits the identification information of the related services which has been read in step S208 to the service information distribution server 200 (step S209). Note that in step S209, when the service information related to the database 140, the cellular phone 100 transmits the version information of the related service information transmits to the service information distribution server 200 in addition to the identification information of the related services.

Next, the service information distribution server 200 reads the service information of the related services shown in FIG. 12 to a service information database 210 based on the identification information of the related services that has been received. When the service information distribution server 200 receives the version information of the related service information, the service information distribution server 200 reads the service information of the related services of the new version from a service information database 210 (step S210).

Next, the service information distribution server 200 assigns a digital signature to the distribution information using the secret key which is registered in the signature key (secret key) repository 230 after being registered in step S102 of the preliminary processing of service display in FIG. 6 (step S211).

Next, the service information distribution server 200 transmits the distribution information assigned with the digital signature to the cellular phone 100 (step S212).

If the related service information of the new version are not transmitted from the service information distribution server 200 when the cellular phone 100 transmits the version information of the related service information to the service information distribution server 200 in step S209, the cellular phone 100 reads the related service information from the database 140 (step S213).

Next, the cellular phone 100 deletes the unneeded data stored in the database 140 (step S214).

Next, the cellular phone 100 registers/updates the distribution information received in the steps S206 and S212 to the database 140 (step S215).

Next, the cellular phone 100 displays services registered in the cellular phone 100 based on the main service information among the distribution information received in step S206, and the related service information among the distribution information received in step S212 (step S216), and ends this processing.

Following to the processing of displaying services in FIG. 7, the cellular phone 100 transmits the identification information of the main service which has been read from the memory area of the storage device 184 of the IC chip to the service information distribution server 200, and receives the main service information and the information for specifying related services from the service information distribution server 200. Further, the cellular phone 100 reads the identification information of the related services based on the information for specifying related services that has been received, transmits the identification information of the related services that has been read to the service information distribution server 200, and receives the related service information from the service information distribution server 200. Then based on the received main service information and the received related service information, the cellular phone 100 displays services registered in the cellular phone 100, that is the cellular phone 100 displays all the services including services which uses the memory area of the IC chip but does not use applications. Thus users can view all the services registered in the cellular phone 100.

FIG. 8 is a flow chart showing a processing of related service identification executed in step S208 in FIG. 7.

In FIG. 8, the cellular phone 100 determines an object to be identified for specifying the related services based on the information for specifying related services among the distribution information which has been received in step S206 (step S301).

As the result of the determination in steps S301, if the object to be identified is data in the IC chip 120, the cellular phone 100 reads the data on the specific place of IC chip (step S302). Then, the cellular phone 100 specifies related services based on the data that has been read (step S303), and proceeds to a later-described processing of step S308. In step S303, if the data on the specific place of the IC chip 120 is X, it is assumed that a service A exists as a related service, or is registered in the cellular phone 100.

As the result of the determination in step S301, if the object to be identified is an existence as an application, the cellular phone 100 confirms the existence of a specific application in the application manager 130 (steps S304). The cellular phone 100 specifies related services based on the confirmation result of the existence of the specific application (steps S305), and proceeds to a later-described processing of step S308. In step S305, regarding to a name of the specific application, for example, if the application exists, it is assumed that the service A exists as an related service, or is registered in the cellular phone 100.

As the result of the determination in step S301, if the object to be identified is a usage history, bookmark or the like of the web browser 110, the cellular phone 100 searches the usage history, bookmark or the like of the web browser 110 (step S306). Then the cellular phone 100 specifies related services based on the result of the search for the usage history, bookmark or the like of the web browser 110, and proceeds a later-described processing in step S308. In steps S307, regarding to the usage history of the web browser 110, for example, if there is a book with a bookmark of page “a”, it is assumed that a service A exists as a related service, or is registered in the cellular phone 100. In step S307, regarding to the usage history of the web browser 110, for example, if there is the usage history within last seven days, it is assumed that a service A exists as a related service, or is registered in the cellular phone 100.

In the following step S308, based on the information for specifying related services among the distribution information which has been received in step S206, the cellular phone 100 determines whether or not all the related services are specified. If all the services are not specified (No in steps S308), the cellular phone 100 returns to the processing of step S301. If all the services are specified (YES in step S308), the cellular phone 100 ends this processing.

[A Processing of Displaying Other Services]

Hereinafter, a processing of displaying other services that the information processing system 1000 according to the present embodiment performs will be explained. This processing is a processing which is performed by the client application installed into the cellular phone 100. FIG. 9 is a sequence diagram showing a processing of displaying other services according to the present embodiment. The processing of displaying other services in FIG. 9 is a processing performed when the cellular phone 100 and the service information distribution server 200 are both offline, and cannot communicate. Note that FIG. 11 is an illustration for illustrating a detail on the processing of displaying other services in FIG. 9.

In FIG. 9, at first, the cellular phone 100 reads identification information of the main service, such as a segment information of the memory area, for example, from the memory area of the storage device 184 of the IC chip 120 (step S401).

Next, the cellular phone 100 reads the main service information and the information for specifying related services from the database 140, based on the identification information of the main service which has been read in step S401 (steps S402). Note that the cellular phone 100 verifies a digital signature assigned to the main service information and the information for specifying related services in step S402. Thus, defacing of the information stored in the database 140 can be detected.

Next, the cellular phone 100 performs a processing same as the processing of related service identification which is performed in step S208 of the processing of displaying services in FIG. 7 (step S403), and reads the identification information of the related services that uses the memory area.

Next, the cellular phone 100 reads the related service information from the database 140 based on the identification information of the related services which has been read in step S403 (step S404). Note that a digital signature assigned to the related service information is verified in step S404.

Next, the cellular phone 100 deletes the unneeded data stored in the database 140 (step S405).

Next, the cellular phone 100 displays services registered in the cellular phone 100 based on the main service information which has been read in step S402 and the related service information which has been read in step S404 (step S406), and ends this processing.

Following to the processing of displaying services in FIG. 9, the cellular phone 100 reads the main service information and the information for specifying related services from the database 140 based on the identification information of the main service which has been read from the memory area of the storage device 184 of the IC chip 120. Then based on the main service information and the related service information which are read, the cellular phone 100 displays services registered in the cellular phone 100. Thus even in the case when the cellular phone 100 and the service information distribution server 200 are both offline, an advantageous effect same as the one in the processing of displaying services in FIG. 7 can be expected.

Note that the above embodiment can also be realized when the IC chip 120 is removed from the cellular phone 100 and is mounted to other different cellular phone 100.
